What is a Mac Address?

A Mac Address, also known as a Media Access Control address, is a unique identifier assigned to a network device like a computer, smartphone, or tablet. Every network device has a unique Mac Address that is used to uniquely identify it on a network. It is a six byte (48 bit) hexadecimal number that is usually written in pairs separated by colons, for example: 00:1A:4B:2F:3C:5D.

In addition, if you want to add an extra layer of security to your device, you can use the Mac Address to set up MAC address filtering on your router. This will only allow devices with specific Mac Addresses to connect to your network, making it more secure.
